Basophils enhance immunological memory responses

Academic Article

Abstract

  • The cellular basis of immunological memory remains a controversial issue. Here we show that basophils bound large amounts of intact antigens on their surface and were the main source of interleukins 6 and 4 in the spleen and bone marrow after restimulation with a soluble antigen. Depletion of basophils resulted in a much lower humoral memory response and greater susceptibility of immunized mice to sepsis induced by Streptococcus pneumoniae. Adoptive transfer of antigen-reactive basophils significantly increased specific antibody production, and activated basophils, together with CD4+ T cells, profoundly enhanced B cell proliferation and immunoglobulin production. These basophil-dependent effects on B cells required interleukins 6 and 4 and increased the capacity of CD4+ T cells to provide B cell help. Thus, basophils are important contributors to humoral memory immune responses.
